The PaXini PXDex III is a three-finger end effector designed for collection-execution isomorphism with the PXCap III glove. Weighing 836 g with 4 degrees of freedom, it features a 6D Hall array multidimensional tactile sensor with 0.1 N accuracy, PaXini self-developed high-precision anti-magnetic encoders with ±0.15-degree accuracy, and dual 170-degree ultra-wide palm RGB cameras at 1080p 30 fps for close-range hand-eye coordination. It delivers 5 kg maximum load with 55 mm maximum grasp and 2 mm minimum pinch diameter. Coreless motor driven, it operates on 19 to 48 V DC and targets research applications for robotic manipulation.
